In 1987, Orrin Frink introduced the concept of almost Pythagorean triples. He defined them as an ordered triple (x,y,z) that satisfies the equation x2+y2=z2+1 where x,y and z are positive integers. In his paper, he showed that there were infinitely many almost Pythagorean triples by giving a characterization which suggests a method on generating all of them. However, this method does not explicitly and readily give a particular almost Pythagorean triple. In this note, using basic algebraic operations, we extend his result by giving a characterization that explicitly and readily give a particular almost Pythagorean triple.
